Hi - Can my meat chickens of seven weeks eat cracked corn as a supplement with their normal grain pellets? They are eating so much now, I'm looking at cost cutting. Thanks! Scotty M.
Sure you can, but corn is a high energy food, it's not a balanced diet and it's low in protein, and thus should be treated as a treat consisting of no more than about 10% of their balanced diet... AKA you can mix 10 lbs of corn into 100 lbs of balanced feed, any more and you can start to see their growth slow down or stunt and or other possible ailments appear...
To be blunt, you won't save any money feeding them corn, because the pounds of feed vs weight gain will plummet, you will need to feed them 2 or 3 units of corn to see the same weight gain you see with 1 unit of balanced grower feed... This is because protein is what builds meat and corn only has about 7% protein (unbalanced amino acids), while a balanced grower feed has about 18-21% (balanced amino acids)... Balanced protein content is very important because no matter how much protein overall is in the feed, if there is a shortage of any one needed amino acid in that protein content then that single amino acid will be the determining limiter...
Example your body needs one red, one white and one blue amino acid for digestion... If the feed has 100 reds, 50 whites and 10 blues (160 overall protein units) then blue is the limiting amino acid and you will only be able to make 10 blocks, with 90 reds and 40 whites going to waste aka poop... While a balanced feed of 10 reds, 10 whites and 10 blues (only 30 overall protein units) would still allow you to make 10 blocks with no waist even though it has much lower overall protein... What we see from the example is that even though the first feed had over 5 times the amount of protein it provided no benefit... This is why balance nutrition and a balanced protein content is important...
So even if you are getting corn at $7 a 50lb bag, when you multiply that $7 by 2 or 3 you are likely exceeding what it cost to just get a 50lb bag of grower, and you still lack a balanced diet with that much corn, so much of that is going right out the back end as waist while your birds are likely to suffer from other nutrient deficiencies if they live long enough...
